Food production on present and future saline soils deserves the world’s attention particularly because food security is a pressing issue, millions of hectares of degraded soils are available worldwide, freshwater is becoming increasingly scarce, and the global sea-level rise threatens food production in fertile coastal lowlands. Future of Sustainable Agriculture in Saline Environments aims to showcase the global potential of saline agriculture. The book covers the essential topics, such as policy and awareness, soil management, future crops, and genetic developments, all supplemented by case studies that show how this knowledge has been applied. It offers an overview of current research themes and practical cases focused on enhancing food production on saline lands.FEATURES Describes the critical role of the revitalization of salt-degraded lands in achieving sustainability in agriculture on a global scale Discusses practical solutions toward using drylands and delta areas threatened by salinity for sustainable food production Presents strategies for adaptation to climate change and sea-level rise through food production under saline conditions Addresses the diverse aspects of crop salt tolerance and microbiological associations Highlights the complex problem of salinity and waterlogging and safer management of poor-quality water, supplemented by case studiesA PDF version of this book is available for free in Open Access at www.taylorfrancis.com.

This volume seeks to investigate the representation of the migrant and migration in literary texts and the arts. Through studies that examine works in a range of art forms ‒ novels, theatre, poetry, creative non-fiction, documentary films and performance and video installations ‒ that evoke a variety of historical and (trans)national contexts, the volume focuses on the question of the roles of literature and the arts in representing migration. An important issue considered is the extent to which artistic figuration can act as a counterpoint to social discourse on migrants that often involves stereotypes and reductive views. The different contributions to the volume illustrate that literature and the arts can provide readers and viewers with a space for fluid knowledge production and affective expansion and that within that overarching function, artistic works play three main roles with regard to representing migration: undertaking a socio-political and cultural critique, presenting alternative views to stereotypes that highlight the singularity and complexity of the migrant and providing proposals for different futures.

This review of work at the forefront of the polymer-colloid field includes an introduction to interactions in colloidal systems and introductions to scattering techniques (light, X-ray and neutron), including discussion of the two-colour light scattering technique. Up-to-date advances in the following areas are included: dynamics in polymer colloid composite liquids, dispersions of microgel nanoparticles and dendrimers, dynamics of latexes, theory of colloid dynamics, diblock copolymers, polyelectrolytes, shear thickening in colloid and polymer suspensions, the concept of the critical gel and rheometry near the gel-point, and surface rheology and its relations to the stability of soft colloids. The emphasis is on the close connection between the polymer and colloid fields. Dendrimers, for instance, represent an intermediate system between a strongly fluctuating linear polymer and a solid, dense colloidal particle. Colloidal charged spherical microgels are used to illuminate and test fundamental ideas of polyelectrolyte physics. The articles aim to be accessible to graduate students, postdoctoral workers and research scientists.

This 2 volume 4-part set includes extensive discussions of scattering techniques (light, neutron and X-ray) and related fluctuation and grating techniques that are at the forefront of this field. Most of the scattering techniques are Fourier space techniques. Recent advances have seen the development of powerful direct imaging methods such as atomic force microscopy and scanning probe microscopy. In addition, techniques that can be used to manipulate soft matter on the nanometer scale are also in rapid development. These include the scanning probe microscopy technique mentioned above as well as optical and magnetic tweezers. This will appeal to soft matter scientists at the graduate level and above, condensed matter physicists, chemists, biologists, medical doctors and engineers.
